Should Beginners Buy Used Cars for Practice?

[SanColin]

Beginners can buy used cars for practice. Exterior of used cars: Many people pay great attention to the exterior. In fact, the exterior is the easiest part to deceive in used cars. With current refurbishment and paint repair techniques, it's really hard to tell the extent of paint repairs with the naked eye. Normally, the paint thickness of cars priced above 50,000 yuan is over 120 microns, one layer of spray paint is over 300 microns, and areas with metal repair are over 500 microns. Trunk of used cars: Open the trunk and flip to the spare tire area. Then carefully inspect the rear section of the car. Check if there's a layer of sealant. Generally, sealant is applied manually, making it relatively rough. Most sealants are pink, flesh-colored, or silver-gray. The sealant should look like it was brushed on. This is correct—even though it appears rough, it's an original factory feature.
